Week 16

Through out this week, we looked at how to graph and keep track of acceleration from any given object, in this case a rocket. We watched as a rocket was launched into the air in almost a straight line, and came back down the same way. We learned that in optimul conditions, any object that goes up, comes back down in the exact speed and direction. When graphed, it looked similar to this: _-_ on a V vs T graph. _- -_ We learned that the exact half of the time taken for the whole trip of the rocket is spent going up, and the other half is spend on the decend. I found all this information useful, because of alot of the activites i participate in involve knowing how objects accelerat in the upward direction. For instance, when a friend and i are in my back yard with a big bundle of bottle rockets, we can look up and see that there is a small gap between the trees that would allow the rocket to safley go up. We now know that when the rocket goes up, it will come down in the same direction at the exact same time. Unfortunatly, we didnt count on the wind that was out that day so im not going into detail on that story. We also learned how to grapgh out the acceleration a rocket gains as its flying through the air. We learned that in most cases of the examples we were learning, the rocket accelerated 10M/S/S which means that for every second, the rocket goes 10m/s faster. So its moving 10m/s, then 20M/s then 30m/s, then back to 10m/s etc as its going back down towards Earth. I found this week very productive for me atleast because the info was very easy to understand and it was something i was espeacially interested in. It was an all new topic, which is why i was very excited about this week.
